SPRAYER ATTACHMENT FOR HOSE NOZZLES.

Application filed 11113719, 1927. Serial No. 206,994.

This invent-ion relates to certain new and useful improvements insprayer attachments for hose nozzles.

The primary object of the invention is to provide a sprayer attachmentfor hose nozzles of the type employed for spraying an insecticide or thelike on growing plants, more particularly cotton and the object of thesprayer attachment is to cause the fluidfiowing through a perforatednozzle to be sprayed fi'l a relatively fine film over increased areasfor the spraying of a plurality of rows of growing plants.

A further object of the invention is to provide a sprayer attachment forhose nozzles wherein the outlet end of the nozzle is of semicircularformation with a single row of spray perforations formed in the curvedside of the head, the sprayer attachment being of semicircular formationand adjustably attached to the spray head of the nozzle in a manner tocause the sprayed film of fluid to issue in different directions fromthe spray nozzle which varies the area being sprayed.

With the above and other objects in View that will become apparent asthe nature of the invention is better understood, the same consists inthe novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawing and claimed.

In the accompanying drawing wherein like reference characters areemployed to designate corresponding parts throughout the several views,

Figure 1 is a side elevational view of a valve controlled hose nozzle,the nozzle head being in the form of a semi-circular chamber with a lineof spray perforations in the curved side thereof and further showing thespray plate supported on the nozzle head in proximity of the line ofperforations for longitudinal and transverse adjustment;

Figure 2 is a fragmentary longitudinal sectional view taken on line 2-2of Figure 1, showing the manner of adj ustably mounting the spray platein longitudinal and transverse directions with respect to the spraynozzle;

Figure 3 is a cross-sectional view taken on line 33 of Figure 1 showingthe screen filtering plate in the spray nozzle.

The spray nozzle disclosed in this application being intended forspraying insecticides or the like over growingplants such as cotton,

' disposed adjacent the curved outer sideof the the hosel is incommunication with a source of supply under pressure of the desiredfluid, the hose 1 communicating with the control valve 2 that has afitting 3 attached thereto which carries the nozzle 4. The valve 2controls the flow of the insecticide to the nozzle 4.

The fitting 3 is enlarged at its outer end and externally threaded whilethe inner end of the nozzle 4 is provided with an annularflange 5 thatcarries an internally threaded collar 6 that is engaged with the threadsupon the adjacent end of the fitting 3 for securing the nozzle to thefitting.

As shown in Figures 2 and 3, a filtering screen 7 is interposed betweenthe fitting 3 and nozzle 4.- and is retained in position by the gasket8.

The nozzle 4 tapers toward its outer end and carries a discharge head 9in the form of a hollow chamber that is semi-circular in plan view withthe curved side thereof being forwardly positioned, while the curvedside of the discharge head 9 is provided with a single row ofperforations 1O extending the entire length of the curved side andsubstantially midway between the upper and lower edges thereof.

A sprayer attachment is adjust-ably connected to the nozzle head 9 in amanner to cause the jets of fluid issuing from the nozzle head tocontact therewith and to be sprayed in the form of a relatively thinfilm. The sprayer attachment comprises an arcuate plate 11 with thecurved inner side thereof nozzle head 9, the arcuate plate 11 beingcarried by a curved bracket arm 12 having a forked depending legextension 15 that is clamped by nut and bolt 18 to an angle leg 16depending from the arm 13 indicated by dotted lines in Figure 2 that isdisposed in contact with the lower side of the nozzle head 9 andretained in position by the adjusting screw 14 passing through the forkand threaded into the head.

In this form of the invention, the spray plate 11 is adjustablevertically of the nozzle head 9 and also toward and away from the same,this adjustment being provided by the screw 18 passing through the slotin the leg 105 15 and threaded through the part 16.

With the spray plate 11 positioned as illustrated in Figure 1, the jetsof fluid issuing through the perforations 10 in the nozzle head contactthe plate 11 and the plurality of no jets are converted into arelatively thin film that is sprayed over a comparatively wide area. Byadjusting the spray plate 11 with respect to the nozzle head 9, theseparate jets issuing through the nozzle perforations contact thesprayer plate at different points to cause a greater or lesser throw ofthe converted film. With a device of this character, a continuous sheetof insecticide or like fluid is sprayed over a greater area than wouldbe possible With the use of a perforated nozzle alone as the plateattachment converts the separate jets into a thin film resulting in acontinuous sheet of the substance being sprayed.

While there is herein shown and described the preferred embodiment ofthe present invention it is nevertheless to be understood that minorchanges may be made therein with out departing from the spirit and scopeof the invention as claimed.

What I claim as new is In a device of the class described a spraynozzle, an enlarged chambered head of semicircular formation having arow of perforations in the forward curved side thereof, an arcuate sprayplate carried by the head against which the separate spray jets arecaused to impinge to convert the jets into a film, and an adjustableconnection between the spray plate and nozzle head to vary the positionof the spray plate relative to the head perforations comprising an anglemember connected to the nozzle head and adjustable longitudinallythereof and a bracket connected to the angle member and adjustablevertically thereof whereby the spray plate is shifted in two directionsrelative to the head perforations to produce sprays of differentcharacteristics.

In testimony whereof I afiin my signature.

JOHN KEG.
